Problems solved by technology

[0013] The handover methods used in existing systems using access codes and / or ranging codes (such as the IEEE802.16e / D5 specification) do not make full use of the signaling channels between base stations, and there are many steps in the handover process. The real-time performance is unfavorable, and there is a certain waste in the use of channel resources on the air interface

Embodiment

[0046] In the IEEE802.16e / D5 specification, a reference message sequence diagram (MSC) including network-assisted handover process requested by the base station and determined by the user station is given, that is, Figure E.11 of the IEEE802.16e / D5 specification. In the present invention, as image 3As shown, the reference message sequence diagram (provided by the IEEE802.16e specification) including the network-assisted handover process requested by the base station and decided by the subscriber station.

[0047] The implementation steps to apply the fast switching method in this case are as follows Figure 4 As shown, the part where the fast switching method is added is specially marked.

Abstract

A rapid switchover method realized by a designated location code includes the steps: a user station sends out switching request to a target station by a current service base station using the signaling channels among the base stations, the target base station designates 'quick switchover measurement code' for the user station and / or the area it is located and the user station launches switchover request with the' quick switchover measurement code ' to the target station. According to the detected code, the target station receives relevant information of the user station for switchover. Among the existing communication systems using access codes and / or location code, such as broadband metropolitan area network standard (IEEE 802.16e standard. HIPERMAN series standards), users can reduce the information exchange between user's station and the target base stations.

Description

technical field [0001] The invention relates to a wireless communication system using an access code and / or a distance-measuring code, in particular to a method for realizing fast switching by using a designated distance-measuring code. Background technique [0002] Access code: refers to the code word used for access (including initial access, periodic access and other access operations) and switching in the wireless communication system. By using the access code, the system can identify the user's Various requests such as access and switching. [0003] The access code is also called a ranging code (Ranging Code) in some documents. In this paper, unless otherwise stated, the two are used equally. [0004] In systems using access codes and / or ranging codes, a subscriber station may use the access codes and / or ranging codes to initiate a handover procedure. For example: IEEE802.16 is a broadband wireless metropolitan area network specification, IEEE802.16e is an extension m...
